Abstract
Monoparticulate layers of dodecylbenzenesulfonic acid-stabilized, 34.0-, 29.4-, and 26.5-A-diameter CdS clusters have been formed at air-water interfaces in a Langmuir film balance. Surface pressure vs surface area isotherms and Brewster angle microscopy demonstrated that increasing surface pressure resulted in transitions from well separated to well-compressed monoparticulate layers and, ultimately, to multiparticulate layers. CdS particles with diameters of 34.0, 29.4, and 26.5 A formed films with critical areas per particle (conceptually analogous to headgroup areas) of 1100, 800, and 650 A 2 , respectively, which corresponded well to the values calculated by assuming hexagonal close packing of hard spheres (887, 749, and 608 A 2 )
